This is met with in dogs used constantly for stud purposes. The scrotum becomes red, spots appear, discharging serum and irritation is severe. The part finally becomes swollen, very sore, the discharge drying forms scabs, which come off, leaving sore patches, and granulation is very likely to appear. On the first appearance of any irritation bathe parts with warm water and administer a mild aperient. After you have well dried the parts, dress morning and night with boracic ointment, and put muzzle on dog to prevent his licking it off. If granulations exist touch with nitrate of silver. If the trouble recurs, as it often does, repeat the treatment.
